It's taken me eight years to find this video.. The series is very easy to understand and the code solves a number of problems I was having with Arduino MIDI. I have been using an Allen Heath ZEDR-16 that has excellent MIDI capability - or did until the Firewire board died and A&H have no stock. I need to build a 16 fader channel with 32 buttons. I reckon I can add a routine to flash an LED on detecting MIDI activity, but extending the buttons to 24 by adding another mux is probably beyond me. Maybe I can build two of these with 16 buttons, set them to different MIDI channels and have the DAW buttons respond to the different incoming channels.

So I don't normally leave comments on videos, but this is without a doubt the best explanation on basic multiplexing I have seen! Concise and clear amongst videos that try and explain this in 1 minute or one hour. You've got yourself a new subscriber and paton :)

I made a midi arduino footswitch using this design; made it all in one night. Was having trouble figuring out how to have my computer read the MIDI messages, but I figured it out.
The video I was watching to figure out the programming for my arduino was by Nick Leonard who adopted your code. After seeing this video it all came full circle. Thank you so much for your work; it's so useful and informative.

DUDE ITS LITERALLY THE BEST EXPLANATION I HAVE EVER SEEN... YOURE THE BEST

[brianmichaelfuller]

No doubt one of the best made videos on this stuff!!! Clear, concise, complete and professional!!! Thank You

[marinkojukic]

So far the best video and best channel for this stuff!

You are such an amazing teacher. Thanks to you, from literally zero electronics experience, to building a custom MIDI controller in a few days. Your instructions and videos are so clear, and you get straight to the point. Thank you from the Small Island across the pond :)

Dude!!!! You speak to me as a beginner and now I finally get it!!! Thank you!!!

[vegansynths]

I had no idea what a multiplexer was and you explained it so clearly and accompanied it with extremely clear visuals and graphics. Thank you for teaching me this.

[donkeystudio]

i am pretty new in the technical side of midi and got curious about the arduino. after some checking i actually wanted to stop because it was so messy information for beginners everywhere, but you saved my plan! aagreat videos, thank you very much to be one step closer to my daw footswitch controller!

[damionmortenson]

, ,Here's how you describe a button:
Start the line with the command word button to indicate that this is a button object.''
I love how a superior language that has such a great accuracy (programming languages) makes smart people sound like their suffering from a stroke. great video. Keep it up...

[tallgeese]

This brings back fond memories of my electronics design days, many years ago.

[victorrey]

so many tanks from france! i make an midi controler for ableton in 2 days and it's work perfectly at the first try... so amazing tutorial and perfectly code!

[itscrawford]

Wow this was amazingly well done. Coming accross a straight forward, well formatted tutorial with clear diagrams narrated by a clear, well spoken voice is like finding a Unicorn in a garbage dump. 10/10 - SUBSCRIBED.

[onpatrolforthejuice]

thank you so much. I just ordered all the stuff to make a 16 step sequencer which will each have an on-off button, a knob for pitch, and a knob for velocity (or some other modulations) I'm really grateful to get such detailed instructions.

[EricBalcon]

Our Dave is the best !, I love the clarity of your explanations, you rock !

[AlexusDelphi]

This helped me finally understand multiplexers

[DirtyCasual]

I'm a pharmacy student, meaning I have ZERO knowledge about electronics or programming. With that said, the fact that i can easily understand everything you just said just speaks about how great this tutorial was! Thanks man!

[shogunai]

Man, you're a genius. I feel like I'm getting much closer to figuring out how Keybed matrixes work. I'm trying to fuigure out how to connect a 61 key Fatar keybed to the arduino, along with 16 x buttons and 16 x pots.

I am seriously hoping you have a video dedicated to that, but I thought I should start at the start! Thanks so much though.

[PatrickJWenzel]

Nicely done! You clarified all the hurdles I had to get me started with Arduino. Very concise and all my intermediate questions were answered along the way, as if you knew I was asking them.
